Deep structure

[Former Member]

Hi

I am trying to create a tree and save this in a structure

I have a structure called st_node and a table called tt_node

I want the following fields in st_node:

ID of type int4.

children_nodes of type tt_node.

adding children_nodes as a type of children_nodes does not allow the structure to activate.

any help pleasE?

recursive typing with data types is not allowed (recursive is only allowed with object types, i.e. type ref to a class or an interface, i.e. abap oo)

instead of converting your program to abap oo, you may also just change a little bit your structure to simulate recursion (for example, add "parent node" field, etc.)
